Feature

●Suitable for circuit board, electronics, SMT, casting, metal processing, telecommunications and other industries. bullet_point
●Bit chip space is large: small chip strength, chip and smooth, heat a small drill, drill reduces pollution
●EXCEPTIONAL CUTTING SHARPTH As a result of nanotechnology and advanced grinding technology, bit sharper cutting edge than before, can reduce cutting force, reduce broken drilling rate, improve hole wall quality.
●Cutting edge strictly symmetrical: advantageous and efficient cutting, avoid offset drilling.
●0.4mm Toughness Cleaning Nozzle Drill Bit for Sharp for 3D Printer Nozzle Accessories

Features:

(1) Precision machining by high-precision equipment.
(2) With good milling and cutting performance to ensure high efficiency.
(3) High hardness, wear resistance and intensity, no bending.
(4) For removing chips, with large space and small resistance.
Smooth chip removal, less calorific value to reduce pollution.
(5) Sharp cutting edge, reduces cutting force, lower breaking rate and improves the quality of the perforated wall.
(6) Symmetrical cutting blade, helps to cut highly effectively, avoids drill offset.

Package includes:
10 x (0.4mm) Drill Bits

Note:
Do not use the drill to clean until the nozzle is heated to over 200 degrees.
